Mercedes-Benz SLS AMG Electric Drive shown in Paris: world’s most powerful production EV

Mercedes-Benz SLS AMG Electric Drive shown in Paris: world’s most powerful production EV

Some time ago, we reported of an electric-powered Mercedes-Benz SLS AMG being given the go-ahead for production. The numbers we had were 526 hp and 880 Nm of torque, which were enough to leave us stunned.

Today we nearly fell off our chairs, for the latest official figures are 740 hp and 1,000 Nm of torque – all from a vehicle with no explosions under its bonnet. In comparison, the petrol-powered SLS AMG GT manages 591 hp and 650 Nm.

Unveiled recently at the Paris motor show, the SLS AMG Electric Drive is touted as the most powerful production EV, as well as the most powerful AMG model, the world has ever seen. It will hit 100 km/h from a standstill in a little under four seconds and proceed to a limited top speed of 250 km/h.

It’s no concept, either – the zero-emissions gullwing coupe is scheduled to hit markets next year. The starting price in Germany will be a cool €416,500 (RM1.6 million). Oh, and before you ask, that body finish is blue chrome. We didn’t know chrome could be had in any other colour except… chrome.

The power comes from four synchronous permanent-magnet electric motors that selectively drive the four wheels through two transmissions (one serving each pair of motors). They’re mounted on the axles rather than in the wheel hubs; Mercedes says wheel hub motors can result in “considerable unsprung masses.” Being electric, power delivery is linear and max torque is available from a standstill – yes, all 1,000 Nm of it.

Feeding the motors is a 60 kWh liquid-cooled lithium-ion battery that generates 400 volts at peak, yielding a 250 km range. It alone weighs a little over half a tonne, so Mercedes has had to adopt a lightweight aluminium and carbon fibre monocoque construction, as well as carbon-ceramic brake discs, to keep the calories in check.

An eerily quiet car cannot be an AMG car, and to that end its engineers have developed a soundtrack that’s piped in through the 11-speaker sound system. The sound is dependent on the driving situation and operating state, in addition to load conditions and road and engine speed. There’s even a start-up sound!

Out go the petrol-engined car’s front double wishbones to be replaced by an independent multi-link suspension with pushrod dampers. The front wheels are 19-inchers shod in 265/35 rubber while the rears are 20-inch, 295/30s.

We never thought we would live to see the words ‘AMG’ and ‘EV’ in the same sentence, but the motor industry never keeps still, does it?

      McDonals have been having (relatively) healthier options on their menu for quite some time now; maybe not so much in Malaysia.
      It is truly the sign of the times and its great to have Mercedes being part of this green(?) movement. Looking forward to more EVs!

        McDonalds serving healthy food? Hahaha! Make me laugh.
        How many MSG, fats in a single burger? All McD are the same.

    Very meaty 1000nm of torque. Can pull a car like a bodybuilder.
    How about trying to pull a truck with this car. Can compete with all the pick up truck in the country

    250 km range if driven sedately.

    At top speed of 250 km/h, how many minutes can the Car go?

      I did some calculations

      700 kW motor
      60 kWh battery capacity

      minutes on full power = 60/700 * 60 = 5.14 minutes.

      At 250km/h,
      I assume around 200 kW should be enough for 250 km/h so

      minutes at 250km/h = 60/200 * 60 = 18 minutes
      enough to get you 18 * 250/60 = 75 kilometers

      Not sure how efficient are the motors but should be around 80 to 90 % efficient. Need to factor that in to be more accurate.

      The problem with electric cars is still the charging. Unless there are special charging stations, its going to take a few hours to charge the batteries.

        mistake read wrongly, full power is only 518kW(740 hp * 0.7) instead of 700 kW.
        so at max power 7 minutes

    Seriously, who the fuck wrote the script for this prorgam? A 6 year old? Almost every single thing the narrator says is? stupid and sounds stupid. Americans really somehow manage to make every single thing they touch turn out stupid especially when it comes to TV prorgams terrible.
